Herman Cain Now the Frontrunner? Afternoon Drive Home

Herman Cain is now the frontrunner by 20 points. That according to a Zogby Poll that puts the former Godfather's Pizza CEO up over Mitt Romney 38 to 18 percent. Ron Paul and Rick Perry are tied for the third position at 12 percent a piece.

Do you think that this kind of lead is real for Cain or will it evaporate?
